Players will be getting the chance to add another weapon to their arsenal in Assasin's Creed III, if you pre-ordered, of course. Gamestop is offering an exclusive download-able mission for customers that have pre-ordered through them.

The exclusive mission takes us down to the ruins of the Mayan Empire in search of Captain Kidd's Sawtooth Sword. Once found, players can use it throughout the main campaign. And in true Assassin's Creed style, there is plenty of running, back flipping, and jump kicking through Old Mexico. Assasin's Creed III will be released for Xbox 360 and PlayStation 3 on October 30 and PC in November.

What do you think? Is the sword and the map worth the pre-order? Let us know on Twitter.
